My quad growing system addresses the need to grow flowers and vegetables in an inexpensive modular system that works where it is impractical or prohibited to grow conventially.
It consists of sets of 4 containers of the same size and shape stacked and nested so that they are portable and have good drainage.
Here in the high desert I have to bury them in the sand to keep the wind from knocking them over.
The white "tulip" shaped irrigation feeds simplify hand watering as I can fill them by hose.
This lily opened today, but birds ate some of the petals before I was able to take a picture. Right of the lily is a Swamp Rose Mallow that I planted last fall and expect to bloom shortly.
